In any collection in the past there is always several odd specimens which do not fit properly.

1. The underside & upperside suggest a cross between a male berenice & a female calauria.
Only a male berenice can pass on the genes for the white ribbon scales giving it its frosted pale blue colour.

Indian ssp showing upper & underside.

I can find no confirmed males of N. berenice with a straight FW band.
Likewise that of N. calauria is almost always straight though a bit of crookedness may be present.

Below the male from Phetchabun is actually kurava .

FW submarginal spots 4 & 5 are triangular esp females in calauria. HW only submarginal spots 4 & 5 have points.

FW submarginal spots 4 & 5 are chevron, more 'V' shaped in berenice . HW submarginal spot 3 or all the spots may be pointed.
The Biodiversity of Singapore website's N. calauria is almost certainly a male N. berenice.


I will like to show another anomaly.

The strong dark striae within the bands is indicative of N. berenice, but the innermost costal spot is missing.

In contrast N beroe male have the dark striae near obsolete & the upperside deeper violet blue.

2. Nacaduba berenice.
The crooked FW band & the narrow V submarginal spot 4 & 5 are typical.


3. Lassipa tiga.
No L. heliodore have the tongue spot cutting across the cell bar.
in L. tiga FW submarginal spot3 is at least 2X the width of spot 4 in both sexes.

In L. heliodore.
FW submarginal spot 3 is almost as wide as spot 4 in the male , but wider by half in the female.

TL Seow; Cheers.
PS. The identification of butterflies is based on the male.
Thus 1 is considered a male N. berenice.
